Gustavsson turned aside 26 of 31 shots during Thursday's 6-4 loss to the visiting Penguins.
Gustavsson will be expected to carry a bigger load with starter Marc-Andre Fleury (upper body) going on injured reserve Wednesday. The 24-year-old Gustavsson had been solid during his opening five appearances, registering a 2.81 GAA and a .914 save percentage. But, including Thursday's loss, he has only one win. Gustavsson, who yielded three third-period goals, fell to 1-4-1 as the Wild dropped their third-straight game.
